To all whom z't may concern.

Be it known that'we, GEORGE F. BIHN and ALBERT J onns, citizens of the United States, residing at Philadelphia; in the county of,

Philadelphia and State of Pennsylvania,

have'inveiited certain'new and useful Im.-.

proveinents in Apparatus for Elevating Liquids, of which the following is a specification.

Our invention relates particularly to that class of apparatus which isshown and ole-f United States Patent.

scribed in our 7 #1,191,4;93, granted to us July 18, 1916, and is especially directed to the valve which is automatically actuated to eflect the raising of liquid.

The principal objects of our invention are to provide a liquid raising apparatus with an automatically actuated valye,'wh ch is of simplified construction, positive and sens tive in its action, durable and inexpensiveto maintain.

it Other objects of our invention are to provide afloat actuated air controlling valve that will not air lock and which is capable of cooperating with a check-valveof minimum capacity. Our invention further comprehends'a valve so constructed and: arranged as to be easily taken apart and assembled and consequently having its working parts readily accessible.

Specifically stated, the form of our invention as hereinafter described, comprises a float actuated valve having opposed air inlet and outlet ports and a reciprocatory pise ton arranged to cooperate with suitable l valve seatsto alternately close said inlet and outlet ports, and having peripheral guides arranged to maintain it in proper alinement to cooperate with said seats.

In the accompanying drawings, Figural is a diagrammatic elevational view of a pneumatic liquid lifting apparatus, conveniently illustrating the application of our in vention' thereto; Fig. 2 is'a vertical longi-' tudinal sectional 'view taken centrally through the automatically actuated controlling valve; Fig. 3 is a plan sectional view permitted to flow by gravity through said pipe 2 and check-valve 5. r p

The outlet of the storage reservoir 1 is conveniently controlled by the plug 6. which has the stem 7 guided by the bracket ,8, and having at its upper end connection with the lever 9, which is fulcruined upon the bracket 10, said lever 9 being connected by a link 11, having a threaded free end which is provided with a winged nut'12 adjustable in cooperative relation with the bifurcated projection 13. The rate ofdischargethrough the pipe 2 may therefore be accurately controlled by the manipulation of said winged nut 12, as is obvious',to permit flow through the pipe 2 and check-valve 5 in the direction of the arrow shown. The air pressure or blow casing 3 is aclosed receptacle having the pipe 15l'eading from the bottom of said casing upwardly into the non-splash nozzle 7 16, which delivers theliquid frorn'the cas- "inpi 3 into the receiving reservoir 17;

he liquid which flows into the blow casing 8 is arranged to be forced therefrom upwardly into. the receiving reservoir 17 by compressed air which isautomatically 0011 cal seat" 26 for the recipro'catoly valve plunger 27, whose depending conical projecting plug 28 is arranged to close the ports 29 and 30 leading into said opening 25 through the conical seat 26 from the annular groove 23, which forms the air'passagc connected with a suitable source of compressed air through the opening 32 and pipe 33 connected therewith.

As best shown in Fig. 3, the valve seat 26 is provided with a plurality of grooves or recesses 34 which permit the free escape of compressed air when the valve plunger drops into its seat 26, thus avoiding any tendency of the valve to spin or chatter.

The liquid in the blow casing may enter the valve chamber through the surge holes 31- may force the liquid from the blow casing 3 through the pipe 15 to the reservoir 17 As best shown in Fig. 4:, the reciprocatory plunger 27 is formed of a central cylin: der 39 having the circular flange 40 of nearly the diameter of the bore of the valve chamber and also having. a plurality of radially disposed wings 42 extending in longitudinal planes and aflording guides loosely engaging the wall of the dome 38, by which the valve plunger is maintained in proper alinement to cause the conical projecting plug 28 and annular boss 35 to properly ur invention is advantageous'in that by providing the upper valve seat 36 of minimum area, the checkrvalve 5 may likewise be of minimum capacity without danger of the valve plunger becoming air locked when the liquid from the reservoir 1 flows into engage their respective seats.

the blow-casing 3. In other words, by reason of the fact that said valve seat is of minimum area, the valve plunger responds instantly when the liquid in the blow casing has been exhausted and the pressure therein relieved, which causes the conical valve plug to immediately shut off the supply of compressed air in the ports. 29 and 30.

It. willbe seen thatwhen the receptacle is filled, the liquid, when rising beyond the uppermost part of the receptacle reaches thegfloat of the air device. The-combina tion of two compressed air pressures facing each other and i the liquid forcing up against the bottom of the float, causes the float to dislodge from its sealed seat of the apparatus. lVithout air pressure coming in through two port holes in the bottom seat of the air device, the liquids alo e compressed airadmitted' could not raise the float and without the aid of liquid the two air pressures could not lift the float. lVith one port hole clogged or closed off, the device in conjunction with the force of the liquid on the float, refuses to lift the float The combination of liquid and air pressure and correct weight of float must be exact or the apparatus cannot operate. After the float seals the exhaust by means of the top seat, the liquid is forced from the device into the receptacle and the air pressure alone coming through the two port holes in the bottom seat of said device causes the float in its sealed position to stayin this position until the entire contents of liquid have been forced by the two air pressures through the discharge pipe to its destination. a a i W hen spent compressed air contained in the receptacle releases itself through dis charge pipe of said receptacle and spent compressed air in the receptacle releases, so

that the air pressure remaining in receptacle-is equal to the weight of the float, the float immediately drops of its own accord to the-bottom'seat, closing ofl? the two com-v pressed air ports. I

It may behere noted that the valve body being constructed of a disk having an annular groove forming a, compressed air passage-way, permits of "the ready access to the passage-ways upon removal of the dome of the valve for cleaning purposes, and affords agreatly simplified construction. i a 4 lVe do not desire to limit our invention to the precise details of construction and arrangement herein set forth, as it is obvious that various modifications may be made therein without departing from the essential features of our invention as defined in the appended claims. U

Having thus described our invention, we claim:'. V

1. An apparatus of the class described, comprising a valve casing having inlet and exhaust ports, provided with seats, a floating valveplunger arranged to alternately.

close said inlet and exhaust ports, and having an annular boss cooperative with one of said seats, a conlcal plug cooperative with the other seat,acircular flange of slightly less diameter than the valve chamber, and a plurality of radially extended wings projecting radially beyond the periphery. of saidfiange.

2. An apparatus of the class described,

comprising a valve casing having, aconicalvalve seatprovided with ports and having passage-ways in its surface intermediate of said ports to form a bypass into the valve chamber andto relieve air pressure, and a valve plunger having a plug cooperative 4. A valve plunger having a cylindrical core provided With a circular flange, and having a plurality of radially extending Wings projecting slightly beyond the periphery of said flange.

In Witness whereof, We have hereunto set our hands the 12th-day of August, A. D.
